BETWEEN Type not working, MetaArray value needs to accept Array values?

[a-zog]

Hi, thank you for the great work you've did !

I would like to have a query that returns all the "Events" that are happening during the next weekend.

This is the query I've crafted:

query getEvents(
  $perpage: Int!
  $weekend_start: String!
  $weekend_end: String!
  $after: String
) {
  this_weekend: events(
    first: $perpage
    after: $after
    where: {
      metaQuery: {
        relation: OR
        metaArray: [
          {
            key: "date_start"
            compare: BETWEEN
            value: [$weekend_start, $weekend_end]
          }
          {
            key: "date_end"
            compare: BETWEEN
            value: [$weekend_start, $weekend_end]
          }
        ]
      }
    }
  ) {
    nodes {
      __typename
      date
      title
    }
  }
}

I've encountered an "Internal server error" issue.
I suspect that is due to the fact that the value property doesn't accept array values.

Would you please help me with this?

@a-zog I'm thinking instead of BETWEEN you might want BEFORE and AFTER?

Something like:

metaArray: [
          {
            key: "date_start"
            compare: AFTER
            value: $weekend_start
          }
          {
            key: "date_end"
            compare: BEFORE
            value: $weekend_end
          }
        ]

Or something along those lines?

It does seem that this meta query plugin should accept one or more values for the value input though, since WP_Query allows it. 🤔

I've suspected that because I've found this code in the MetaArray fields definitions.

$type_registry->register_input_type( $type_name . 'MetaArray', [
    'fields' => [
       ...
        'value'   => [
            'type'        => 'String',
            'description' => __( 'Custom field value', 'wp-graphql' ),
        ],
       ....
    ]
] );

I can either implement BETWEEN or a combination of OR / AND (example here) so I'm sure that all the cases are covered. None of these would unfortunately work.

$args => array(
        'relation' => 'OR',
        array(
            'relation' => 'AND',
            array(
                'key' => 'event_date_start',
                'value' => $weekend_start,
                'compare' => '>='
            ),
            array(
                'key' => 'event_date_end',
                'value' => $weekend_start,
                'compare' => '<='
            )
        ),
        array(
            'relation' => 'AND',
            array(
                'key' => 'event_date_start',
                'value' => $weekend_end,
                'compare' => '>='
            ),
            array(
                'key' => 'event_date_end',
                'value' => $weekend_end,
                'compare' => '<='
            )
        ),
    )
);
